"During the second quarter of our fiscal year 2017, we have been focused on near term orders and their associated revenue, now closer than ever, and we are in the midst of forming financially impactful business platforms, all of which have been made possible by the successful multi-year commercialization of our technology," said DeLome Fair, SES President and CEO. "Projects on nearly every continent are seeking us out, and I am extremely excited about the progress we are making through our technology projects and platforms outside of China. These inquiries are from countries and regions around the world eager for an economic alternative to expensive natural gas that is also environmentally responsible. SES Gasification Technology delivers a cleaner use of coal - a greener
solution - that is proven on over 50 coals, biomass and wastes, including feedstocks from the US, Europe, China and Australia."

Ms. Fair continued: "Today, from our most advanced project bidding activities to early stage commercial discussions, SES is working a project pipeline with current prospective opportunities that could exceed $20 billion dollars in total project facilities cost. Our nearest-term activities include the South American project that continues to move forward, and multiple new potential projects - in India, the Caribbean, and Southeast Asia. We
believe that total installed cost of these projects could exceed $2 billion beginning this year and extending across the next three to five years.

"Based on our success with the approach on the Australian Future Energy platform, we are continuing to develop business platforms in regions of the world with abundant low-cost lignite coal and coal wastes and limited access to affordable natural gas. We intend to move into Eastern Europe with a similar type of platform structure in the near future. Additionally, we believe there will be future opportunities for platforms in other similar regions, such as India," added Ms. Fair. "We intend to utilize the same platform concept in China where we have spent the majority of our
efforts over the past ten years. We are working diligently on completing one or more self-funding China platforms with strong Chinese investment partners who are interested in taking our China assets, partnerships and future project opportunities that we have developed to the next stage, which will allow our Chinese operations to run relatively autonomously from SES. Once successful, our goal is to participate in China's energy growth through co-ownership of the project investment platform and technology license orders."

Recent Corporate Highlights

SES Assets:

Callide Mine: In October 2016, Batchfire Resources Pty
Ltd., in which SES holds an approximately 11% ownership position, completed its acquisition of the Callide thermal coal mine located in Central Queensland, Australia, from Anglo American plc. The Callide Mine is a mature and significantly sized coal producer with substantial recoverable thermal coal reserves, according to Batchfire. The mine continued its operations uninterrupted on a "walk-out, walk-in" basis, and reports from the early operation of the mine since the acquisition are showing a smooth transition. Our ownership position in Batchfire is the result of our successful platform development activities in Australia.

Yima Joint Ventures Methanol Plant: The Yima plant returned to operations in
November 2016, with good operation reports since the restart. Yima JV management continues its efforts to consolidate the JV structure, in order to finalize the permits and move forward with the plant's official operations phase. SES is pursuing options to monetize this asset.

Chris Raczkowski, an accomplished leader and engineer whose career focus on clean energy technologies includes 17 years of professional experience and living in China and Southeast Asia, joined the team as President - Asia, as announced in December 2016. Mr. Raczkowski's 25-year career includes energy project development in China, Vietnam, Thailand and Malaysia, and he served as Vice President Engineering for SES during the development and construction of the SES Gasification Technology demonstration plant in Shandong Province, China.

Fiscal Second Quarter 2017 Financial Results (Unaudited)

The Company reported revenues of $5,000 for the Current Quarter. During the Comparable Quarter total revenues were $53,000, which resulted from engineering feasibility studies and
coal testing services for a customer.

The Company reported $2,000 costs of sales during the Current Quarter. In the Comparable Quarter cost of sales totaled $35,000, which related to the costs incurred for coal testing and engineering studies for a customer.

The Company's operating loss from continuing operations for the Current Quarter was $2.9 million versus an operating loss of $3.1 million for the Comparable Quarter. The decrease in operating loss was primarily due to less stock-based expense in the Current Quarter.

The Company reported a gain from discontinued operations related to our ZZ Joint Venture of $2.3 million for the
Current Quarter compared with a total loss of $1.0 million for the Comparable Quarter. The Current Quarter gain of $2.3 million was primarily the result of the deconsolidation of the ZZ Joint Venture in the Current Quarter.

The net loss attributable to stockholders for the second quarter of fiscal 2017 was approximately $0.6 million during the Current Quarter versus a loss of $3.9 million for the Comparable Quarter.

As of December 31, 2016, the Company had cash and cash equivalents of $9.3 million and working capital of $8.2 million.
